you asked for this year, well it is all relational. i will take bitcoin as our example since that moves the whole market.
the lowest point of bitcoin this year is $5700 a few days ago and yesterday i saw btc price being $6900 yesterday so that looks like a 21% increase in 10 days
before that in feb we saw prices down to $6000 and then go up around $10,000 which is 40% increase.
thats alot of profits if you had invested on those levels.
